	calc_support_resistance(# list/numpy ndarray/pandas Series of data as bool/int/float and if not a list also unsigned# or 2-tuple (support, resistance) where support and resistance are 1-dimensional array-like or one or the other is None# can calculate only support, only resistance, both for different data, or both for identical data
	h,# METHOD_NAIVE - any local minima or maxima only for a single interval (currently requires pandas)# METHOD_NAIVECONSEC - any local minima or maxima including those for consecutive constant intervals (currently requires pandas)# METHOD_NUMDIFF (default) - numerical differentiation determined local minima or maxima (requires findiff)
	extmethod = METHOD_NUMDIFF,# METHOD_NCUBED - simple exhuastive 3 point search (slowest)# METHOD_NSQUREDLOGN (default) - 2 point sorted slope search (fast)# METHOD_HOUGHPOINTS - Hough line transform optimized for points# METHOD_HOUGHLINES - image-based Hough line transform (requires scikit-image)# METHOD_PROBHOUGH - image-based Probabilistic Hough line transform (requires scikit-image)
